Description
We study the effective action of the scalar position moduli of Type IIB Dp-branes. We find that in many instances the kinetic term is modified by a term proportional to the scalar potential itself. This can be linked to the appearance of higher-dimensional supersymmetric operators correcting the Kähler potential. We identify the supersymmetric dimension 8 operators describing the alpha' corrections captured by the DBI action. An example where this study could be useful in the future is in models of inflation where the inflaton is the position modulus of a Dp-brane.
